Structural Shapes
Structural steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a Profile (engineering), profile of a specific cross section (geometry), cross section. Structural steel shapes, sizes, Chemistry, chemical composition, mechanical properties such as strengths, storage practices, etc., are regulated by Technical standard, standards in most industrialized countries. Most structural steel shapes, such as i-beam, -beams, have high Second moment of area, second moments of area, which means they are very stiff in respect to their cross-sectional area and thus can support a high Structural load, load without excessive Hogging and sagging, sagging. Common structural shapes The shapes available are described in many published standards worldwide, and a number of specialist and proprietary cross sections are also available. *I-beam, -beam (-shaped cross-section – in Britain th ...
